Yes the DNS still exists. I deleted the zone and recreated it, even though the DNS is managed by Cloudflare.
Got the same error message on Install Wordpress +LSCache.
The rest of the sites work, so could this be a caching problem where it is still seeing the old site even though it is is deleted.
This is what the browser sees, so a website definitely does not exist at the url.
For now I put a URL redirect to another domain, so that solves the problem for now.
How about looking into this horrible bug? Whether it is a DNS flushing, caching issue or rules or whatever, we should be able to create a web site with the same domain after waiting 24+ hours.

To which I have deleted the DNS and recreated it.
I have used 1234567 password for the Wordpress site, so that is not any of those not permitted characters, but it still gives this error.
I did not realize the “not allowed iin the input” did not just relate to the the password field, as it is a typical error you see trying to use invalid characters in a password.
The Create Website interface in Cyberpanel does will not allow us to use any othe not permitted characters in any filed on the form. I had an apostrophe in the ‘Site Title’.
After creating the website, I went to the Wordpress dashboard, and changed the Site Title in the Settings.
So this is my own solution. Sorry to cause confusion. I will mark it solved as I 'm sure even as veteran WP users, it caught me, so new users may find this helpful.
